Troubleshooting Disabling the FQDNS grain

The FQDNS grain returns the list of all the fully qualified DNS services in the system. Collecting this information is usually a fast process, but if the DNS settings have been misconfigured, it could take a much longer time. In some cases, the client could become unresponsive, or crash.

To prevent this problem, you can disable the FQDNS grain with a Salt flag. If you disable the grain, you can use a network module to provide FQDNS services, without the risk of the client becoming unresponsive.

On the Uyuni Server, at the command prompt, use this command to disable the FQDNS grain:

This command restarts each client and generate Salt events that the server needs to process. If you have a large number of clients, you can execute the command in batch mode instead:

Wait for the batch command to finish executing. Do not interrupt the process with Ctrl+C.
